Sleep apnea is a sleep disorder that causes someone to pause breathing during sleep. Those suffering from sleep apnea usually don't know their breathing is being interrupted for 10 or more seconds at a time, and it often happens repeatedly throughout the night. This disorder causes a long list of symptoms and health issues, including poor sleep quality, chronic fatigue, headaches, depression, and even high blood pressure and heart disease.
The bad news is that sleep apnea is a relatively common issue that affects millions of people worldwide. The good news is that most sleep apnea can be treated effectively with continuous positive airway pressure (CPAP) machines.
